ΠΑΡΑΜΕΤΡΟΙ ΠΟΥ ΕΠΗΡΕΑΖΟΥΝ ΤΗΝ ΕΞΟΡΥΞΙΜΟΤΗΤΑ ΤΩΝ ΠΕΤΡΩΜΑΤΩΝ ΜΕ ΚΑΔΟΦΟΡΟ ΕΚΣΚΑΦΕΑ

IN THIS DISSERTATION THE PARAMETERS AFFECTING BWE DIGGABILITY ARE INVESTIGATED AND A DIGGABILITY CRITERION IS INTRODUCED WHICH INCORPORATES TWO PARAMETERS, THE EFFECTIVE OUTPUT OF THE BUCKET WHEEL EXCAVATOR AND THE SPECIFIC DIGGING ENERGY OF THE ROCK MASS. THE PROPOSED CRITERION IS FORMULATED BY USING THE SIMULATORBWDIG, WHICH SIMULATES THE DIGGING OPERATION OF A STANDARD BUCKET WHEEL EXCAVATOR WITH A CROWDLESS-TYPE BUCKET WHEEL BOOM, EXCAVATING ACCORDING TO THE FULL BLOCK-TERRACE CUT METHOD. IN ORDER TO COMPARE THE PERFORMANCE OF DIFFERENT BWE DESIGNS, A BWE DIGGABILITY INDEX IS, ALSO, PROPOSED WHICH INCORPORATES THE EFFECTIVE OUTPUT OF THE BWE, THE SPECIFIC DIGGING ENERGY OF THE ROCK MASS, AND THE WEAR RATE OF THE CUTTING TOOLS.
